1. A vehicular control system, said vehicular control system comprising:

  • a camera configured to be disposed at a vehicle equipped with said vehicular control system;

    wherein said camera, with said camera disposed at the equipped vehicle, views exterior of the equipped vehicle;

    said camera capturing image data of a scene exterior of the equipped vehicle;

    a controller comprising a processor that processes captured image data;

    a temperature sensor operable to sense exterior temperature at the equipped vehicle;

    wherein said controller, when said processor processes image data captured by said camera with said camera disposed at the equipped vehicle, detects at least a partial blocking condition at said camera;

    wherein said controller is responsive, at least in part, to an outside air temperature input from said temperature sensor;

    wherein, responsive to the outside air temperature input, said controller switches processing of captured image data between (a) a normal processing mode and (b) a cold weather processing mode;

    wherein, with said camera disposed at the equipped vehicle, and responsive to the outside air temperature input being indicative of the exterior temperature being below a first threshold temperature, said controller processes captured image data in the cold weather processing mode to enhance blockage detection of frost or snow or ice at said camera;

    wherein, when said controller is operating in the cold weather processing mode, said controller switches processing of captured image data to the normal processing mode responsive to the outside air temperature input being indicative of the exterior temperature being above a second threshold temperature; and

    wherein the second threshold temperature is greater than the first threshold temperature.
